I was about to reply to Tuvok that society also needs charity, which I don't define in the modern sense of extraction and tax breaks, but then started thinking - if charity is enshrined in a "base layer" of ethics, then it gets used by people who don't actually need any help to violate people's property.

I think that goes on a second layer of ethics, and must never violate the base layer. People will still be people and will help when they can.
